HOWARD L. BOYD, OF LOS ANGELES, CALIFORNIA.

INCINERATOR.

Application led April 10, 1911.

T 0 all 'wwm it may concern:

Be it known that I, HOWARD L. BOYD, a citizen of the United States, residing at Los Angeles, county of Los Angeles, State of California, have invented new and useful Improvements in Incinerators, of which the following is a specification.

My invention relates primarily to a device for burning garbage, and the object thereof is to produce a simple, inexpensive and efficient device for that purpose. I accomplish this object by the device described herein and illustrated in the accompanying drawing, in which;

Figure 1, is a central longitudinal section of my improved device. Fig. 2, is a section on line 2-2 Fig. l. Fig. 3, is a front end elevation with parts broken away for clearness of illustration. Fig. 4 is a section of a modified form of incinerator taken on the same line as Fig. 2. i

In the drawings, 5 is an outer metallic jacket preferably rectangular in longitudinal horizontal section as shown in Fig. 2, and having an arched top as shown in Figs. 1 and 3. This jacket is provided with refractory lining 6, preferably of fire brick, and forms the incinerator chamber. In the front end, in the center of the front is a burner opening 7 through which projects a hydro-carbon burner S, of any approved construction. Below the burner opening is the refuse opening 9 through which the ashes are removed. This opening is closed by doors 10. In the center of the top, at the rear end is the feed opening 11, through which the garbage is fed into the incinerator. Projecting through this opening and secured to the shell is the feed chute 12. This chute is preferably rectangular and provided with a cover 13, which is removed when garbage is fed into the chute. The chute is provided with a hinged bottom 14, which is normally held closed by chain 15 and counterweight 16. Then the garbage is fed into the chute, the chain is locked in any suitable manner until the chute is full, when the cover is put on, the chain unlocked when the bottom falls downwardly and allows the garbage to fall into the interior. The bottom then swings back into the position shown in Fig. 1. A bottom lining 17, preferably of fire brick, starts from near the center of the rear end and projects sharply downwardly and then forwardly on a sharp grade as shown in Fig. 1, so as to Specification of Letters Patent.

cause any liquids that might be contained in the garbage to drain to the front of the incinerator. This lining preferably rests on a rubble foundation 18. Within the rubble 18,'an air supply pipe 19, runs from the center of the front end of the incinerator near the bottom thereof, to the rear distributing chamber 20, in which chamber it branches, and the branches pass to the sides of the incinerator and then run to near the front, then rising to near the level of the burner and then passing through an opening 21 in the protective wall 22, to a point near the burner where they discharge air for combustion. The elbows 23, of these branches are revoluble so as to change the point of delivery of the air as desired. i

At the front corners of the incinerator chamber and leading from a point above the burner opening are the escape pipes 24, through which the exhaust products of combustion pass. In Fig. 4 the escape pipes 24 run from the front corners of the incinerating chamber and unite and connect with stack 28. These pipes pass downwardly and then rearwardly just below the bottom lining and open into the rear distributing chamber. These pipes pass down behind the protective wall 22. Auxiliary escape pipes 25 lead from the rear distributing chamber to the front distributing chamber 26. A central escape pipe, 27, leads from the front distributing chamber and opens into the stack 28. Where there are a number of chambers used as a single plant the stack would run along the ends of all the chambers at the bottom thereof before rising. The object in having the distributing chambers and the escape pipes just below the lining of the bottom is to utilize the heat from the waste gases in heating and drying the garbage so that it will burn more readily.

By this construction it will be seen that I Ahave provided a simple and etlicient incinerator. By making the units of small size, the cost is small for each unit, and the garbage is always close to the flame. By having a number of units at each plant, any desired capacity may be obtained. It will be observed that the garbage is fed into the incinerator at the center on an inclined bottom which inclines toward the front so that if there are any liquids, they will drain to the front wherethey will be evaporated. It will also be observed, that I use hydro-carbon fuel either in a liquid or gaseous state, and

ing an Q Copies of this patent may be obtained for 5 combustion pass outl through pipes atthe front of the chamber and adjacent to the burner, all gases which carry noxious or noisome fumes are subjected to the action of the flames and burned up so that no smell is 10 produced by my incinerator.

I have shown a central top feed opening as consider that the best way to feed the garbage into the incincrator chamber, but the feed opening may be located elsewhere.

Having described my invention, what l claim is:

1. A garbage incinerator, having an incineratingchamber provided with a burner openin lr in the front thereof and a feed opend a. bottom lining; a front and a rea'r distributingchamber belo74 the bottom lining; pipes connectingv the front and rear distributing chambers; escape pipes extending from each side of the burner opening downwardly'along the front Wall to a point just below the bottom lining thence passing to the, rear distributing chamber; and means to con\-e Y the waste products of combustion from the front distributing chamber.

2. .i garbage incinerator, comprising an outer metallic casing having a refractory lining provided with a feed port in the top rear port-ion and a hydrocarbon burner opening in the front end and a waste opening; a front and a rear distributing chambei' below the bottom lining; escape pipes tending downwardly from each side of the burner opening to below the lining and passing along and belo the same and terminatf ing in the rear distributing chamber; pipes connecting the rear and front distributing chambers; and means to convey .the waste products of combustion from the front dis` tributing chamber.

In witness that I cla-im the foregoing l have hereunto subscribed my namethis third day of April, 1911. HOWARD L, BOYD.
